I’ve been using the NEX-5 with accessory mic – and sometimes, by forgetting to bring it, without. Today we had the Ripon City Morris side in town, and I was taking still shots using the Nikon D3X with the new Nikkor 85mm f/1.4 AF-S G lens. The NEX was grabbed as an afterthought for video.
Well, the wind noise with the built-in mics was just too much; most of my ‘footage’ ended up on the cutting room floor. After I’d got the portraits and other shots I need for the Nikon test, I nipped back to the studio and got a 4.5m high Manfrotto lighting stand fitted with a ball head. The NEX got its accessory stereo mic (set to 90° coverage) and the 16mm lens, and despite the wind level, was hoisted aloft for the last couple of dances in the square. The 30 minutes recording time really helps. My framing was not perfect, so two of the video clips were cropped down from the original 1080p, in iMovie. It is an instant process, just select the clip, select the crop tool and trim.
Despite very definite winds blowing around the pole-mounted camera and mic, there were no wind noise issues at all. So: for outdoor shooting, the accessory mic is essential.
Here is a video made the week before, entirely using the ECM-SST1 microphone, which has no wind noise at all – see this post: ECM-SST1 microphone handheld clips.
